2020-08-24soc/amd/picasso: Reboot for recovery if no psp workbuf is foundMartin Roth
Instead of halting if the vboot workbuf is not passed to coreboot by the PSP, reset and reboot into recovery mode. This process is made more difficult because if the workbuf isn't available, we can't reboot directly into recovery - the workbuf is needed for that process to be done through the regular calls, and we don't want to go around the vboot API and just write into VBNV directly. To overcome this, we set a CMOS flag, and reset the system. PSP_verstage checks for this flag so it will update VBNV and reset the system after generating the workbuf. BUG=b:152638343 TEST=Simulate the workbuf not being present and verify the reboot process.

2020-04-29soc/amd/picasso: Add bootblock supportFelix Held
The original plan for Picasso was to combine the features of bootblock with romstage due to its unique way of coming out of reset. Early in development, all bootblock support was removed from the directory. All Picasso designs will now use a bootblock as their first stage. The reason being that it requires less invasive changes than using a hybrid romstage. Add a basic bootblock back to the directory, and compatible with the design of lib/bootblock.c. The files support RESET_VECTOR_IN_RAM and add appropriate settings in Kconfig. Make Makefile.inc calculates the size and base of bootblock from known parameters. * Future work may attempt to streamline this further, in conjunction with changes in amdfwtool. See b/154957411.

2019-07-02soc/amd/picasso: Create picasso as a copy of stoneyridgeMartin Roth
So that everyone can see what's being updated from stoney, we're starting with a direct copy of the stoney directory. There are arguments both for and against doing it this way, but I believe This the most transparent way. We've moved much of the duplicated stoney code into the soc/amd/common directory and will continue that work as it becomes obvious that we have unchanged code between the SOCs. Makefile.inc has been renamed as makefile.inc so that it won't build in jenkins until the directory is updated. Other than that change, this is an exact copy of the stoneyridge SOC directory which will be updated in the follow-on commits in the patch train.
